Hello,

I’m trying to install Collabora CODE on my server which is running Debian Buster 10. I’m using an Nginx reverse proxy. When I try to navigate with the browser to `collabora.mydomain.com` I get a 404 from Nginx and when I navigate to `https://collabora.mydomain.com` I get the default “Welcome to Nginx!” page. `journalctl -u -f loolwsd` doesn’t show anything when I do it.  
I’ve followed the instructions for the Nginx config [here](https://www.collaboraoffice.com/code/nginx-reverse-proxy/) terminating at the reverse proxy. Correct me if I’m wrong, but the risk of terminating at the proxy is minimal since Collabora should not be exposed towards the outside. Alternatively, would a self-signed certificated between Collabora and Nginx be a good idea?  
I modified the enable and termination settings in the `ssl` tag in the `loolwsd.xml` file.  
I’m using Pydio Cells as well, and when I try to open a document from there with SSL enabled, `journalctl -u -f loolwsd` writes  
` WRN client - server version mismatch, disabling browser cache.`  
`ERR Looks like SSL/TLS traffic on plain http port`

Does anyone have any ideas who can I solve this problem?

Thanks,

Ben
